Under-Slab Drain Leak Repair in Phillips Ranch, Pomona, CA

Why do drains under the slab fail in Phillips Ranch?

An under-slab drain leak is a crack, break or separation in the drain and sewer piping beneath your concrete floor, the pipes that carry wastewater from sinks, showers and toilets. Phillips Ranch is a planned hillside community in southwest Pomona, right next to Diamond Bar, with winding streets, terraced lots and homes on graded pads above or below the street.

For hillside homes, many of them two-story, on terraced lots with retaining walls, drain leaks behave differently from supply leaks. They only leak while water is draining, so the meter will not show them, and over time they can soften the soil under the slab and attract roots.

On terraced lots with retaining walls along winding streets in Phillips Ranch, settling can change the slope of a drain line and create low spots, called bellies, where waste collects. A camera inspection reveals them.

In Phillips Ranch, copper supply lines that have been under the slab since the community was built usually come with drains of a similar age, often cast iron or early ABS plastic. A camera inspection checks their condition while the supply side is being assessed.

In Phillips Ranch, service lines that run up or down slopes, under steps and steep driveways usually come with a long sewer lateral from the house to the street. Problems in that section are handled separately from the drains under the slab.

With two-story plans with hot runs to bedrooms at the far end of the house in Phillips Ranch, drain lines run a long way to the sewer connection. A camera inspection maps the entire route and shows exactly where the problem is.

How is an under-slab drain leak repaired in Phillips Ranch?

1. Run a camera through the drain to inspect the line.

3. Choose between lining, a spot repair or a reroute.
4. Repair or replace the damaged section.

On terraced Phillips Ranch lots, note where the meter, the house shut-off and the irrigation valves sit on the slope, since they can be several levels apart. Ask whether there is an accessible cleanout in your Phillips Ranch home, since that is where the camera inspection usually starts.

What affects the cost of drain leak repair in Phillips Ranch?

Drain repair cost depends on the damage, the depth of the line and whether lining is possible. In Phillips Ranch, slopes, steps and retaining walls make outdoor access slower, and two-story layouts affect how easily a line can be moved overhead. The camera inspection report is the basis for an accurate quote.

Drain and sewer repairs usually require a permit and inspection. For homes in Phillips Ranch, that goes through the City of Pomona.

What should you check after under-slab drain leak repair in Phillips Ranch?
